Coffee Reduces Risk of Heart Disease and Mortality, Study Finds
A recent study conducted by the Southern Medical University based on health data from the UK Biobank project of 170,000 British adults showed that coffee reduces the risk of heart disease and mortality. This finding contradicts previous warnings from the medical community that coffee negatively affects the cardiovascular system. Building on this research, scientists from the University of Melbourne have published a new study in the European Journal of Preventive Cardiology that examines the effects of different types of coffee on heart health. The study expands the sample size to 450,000 people and distinguishes between decaffeinated, ground, and instant coffee.
The researchers found that consuming one to five cups of caffeinated coffee reduces the risk of heart rhythm disorders, while decaffeinated coffee has no effect on their occurrence. People who consume two to three cups of instant coffee or four to five cups of ground coffee per day have the lowest incidence of heart rhythm disorders. The data also shows that both caffeinated and decaffeinated coffee significantly reduce the risk of heart disease, with the lowest risk observed in people who drink two to three cups of ground coffee with caffeine per day. Additionally, the overall mortality rate decreases significantly with all types of coffee, with the greatest risk reduction observed in people who consume two to three cups of ground coffee with caffeine per day.
While the study’s results are limited by the fact that the data on coffee consumption and other dietary habits are based on self-reports, the larger sample size provides more robust evidence for the health benefits of coffee. The study’s authors suggest that further research is needed to understand the mechanisms behind these findings and to determine the optimal amount and type of coffee for heart health. Nevertheless, the study provides encouraging news for coffee lovers who can now enjoy their daily cup of joe with the knowledge that it may have positive effects on their heart health and longevity.
